People forget that the president is running a nation, not a Salvation Army soup kitchen. He has a responsibility to see that the United States prospers, is protected from enemies, and is just. He is not supposed to discriminate against Americans because he has a soft heart for everyone in the rest of the world who admittedly would be better off they were here on our welfare rolls, treated for free in our emergency rooms, getting free education for their children although they have paid no school taxes, and so on.
And THAT is the kind of non-sequitur that is most unfair of all, but which does keep his base loyal. That base does notice the difference between a simple policy disagreement and vengefulness on the part of those who wanted the other candidate to win the November, 2016 election.
